Xterium is a free OGame-like space 4X with multiple universes, alliance wars, and mobile apps synced to the same account.
If you know fleet-save culture from older space browsers, Xterium will feel familiar with its own balance twists. Universes differ in speed and rules, so read the description before investing time.
Alliances again decide the real wars—solo play is possible but limited once the map heats up.
Create an account on the official site, start in a slower universe if you are returning from a break, and secure basic defenses before raiding.
